Hi all first post so be kind!!! I have purchased a tag carrera calibre 16 from trusty a good 8-9 months ago now awesome looking watch and has always kept good time up until a couple of weeks ago when it fell off the table, all dials are still working but it is now 15 minutes out... Example is when it is 12 o'clock it takes 15 minutes for the hour hand to line up with the hour mark Is there something I can do to fix? Part 2 I am now looking at making my second purchase I really want a tag grand carrera calibre 36 but I want it in the yellow version with the leather strap and yellow stitching, I have been trolling this site and the Td's sites and have only come across really bad Quartz versions does anyone here know of a Td that has this version with 7750 chrono?
